The Route Comparison APIs can help you plan routes by considering the time and distance between a series of locations. These APIs include:
- Drive Time Polygon (Isochrones), which retrieves a polygon of the location coordinates that can be reached from a
centerpoint within a specified driving time in
- Route Matrix, which returns the travel time and distance for a matrix of origins and destinations.
To call the Route Comparison APIs, you must have a PC*MILER Web Services API key. Route Matrix also requires an add-on license.
- The Drive Time Polygon API can be called via a GET request.
- Route Matrix APIs can be called via both GET and POST requests.
